[X-ray diagnosis of disturbed bronchial permeability in chronic bronchitis]

The authors presented clinical and x-ray findings of combined investigation of 94 patients with chronic bronchitis. X-ray symptoms of disturbed bronchial permeability (DBP) in this pathology were studied. Bronchograms, bronchosonograms performed in different phases of respiration using broncholytic drugs, video tape recording, coherent-optic processing of bronchograms, and a method of digital processing of bronchograms proposed by the authors were employed. The importance of x-ray examination in the diagnosis of DBP was shown. The classification, nature, site and spreading of DBP were described. X-ray findings were compared with clinical and laboratory findings.
